Elcometer 456 Ultra / Scan Probes
1 GENERAL INFORMATION
The Elcometer 456 Ultra/Scan Probes have been specifically designed for use with the "Scan" and "Auto Repeat"
modes on Elcometer 456 Model T separate gauges. They are supplied with a highly durable 'snap on', user
replaceable, probe cap - allowing users to take individual readings or rapidly scan large surface areas without
damaging the probe or the coating.
Scan Mode: When Scan Mode is selected, users can slide the Ultra/Scan Probe
over the entire surface area. As the probe is lifted off the surface the gauge
displays the average coating thickness value (x) together with the highest (Hi)
and lowest (Lo) thickness values. Each set of three readings can be displayed
on a run graph and stored into the memory. This is ideal for on line inspection.
Auto Repeat Mode: When the probe is placed onto the coated substrate in Auto
Repeat Mode, the gauge automatically takes readings at a rate of 140 per
minute until the probe is removed from the substrate. Each individual reading is
stored into the memory. The Auto Repeat Mode can be used to significantly
speed up the inspection of large coated areas such as steel I-beams (RSJ's),
tanks, ship hulls, etc.
Note: "Scan Mode with Hold" allows the probe to be lifted off the surface for a maximum of 1.5 seconds and replaced without
starting a new set of readings - allowing the user to avoid holes, weld seams, etc. in the substrate without affecting the
measurement results.
